Adding co-authors to Git commits

How do you share credit for a new or altered piece of code when one person commits the change in a pair programming or mob programming session? And when you have questions about a particular change, how can you see in Git who has been working on that change, besides the committer? You add co-autors to your commits. This gist contains information on how to do that, so that the Git commit message contains a list of co-authors, and all co-autors for a commit are automatically listed in GitHubs web UI.

GitHub has some info on specifying co-authors here. This is good info, pretty straightforward. The gist of it (pun intended) is to include at least one blank line and then a line for each co-author like so Co-authored-by: name <[email protected]> at the very end of your commit message.

Tcpdump

Tcpdump is a commandline tool that is used to dump traffic on a network. This tool comes in hand when you want to analyse network captures within the command line. Basically it can do most of the wireshark job.

Using Git Commit Message Templates to Write Better Commit Messages

The always enthusiastic and knowledgeable mr. @jasaltvik shared with our team an article on writing (good) Git commit messages: How to Write a Git Commit Message. This excellent article explains why good Git commit messages are important, and explains what constitutes a good commit message. I wholeheartedly agree with what @cbeams writes in his article. (Have you read it yet? If not, go read it now. I'll wait.) It's sensible stuff. So I decided to start following the

	import { Directionality } from '@angular/cdk/bidi';
	import { CdkStep, CdkStepper, StepperSelectionEvent } from '@angular/cdk/stepper';
	import {
	AfterViewChecked,
	AfterViewInit,
	ChangeDetectionStrategy,
	ChangeDetectorRef,
	Component,
	ContentChildren,
	ElementRef,

	const util = require('util');
	const sass = require('sass'); // `npm i -D sass`
	const renderSass = util.promisify(sass.render);
	const inputFile = '_includes/style.scss'; // the path to your main SCSS file
	const outputFile = 'style.css'; // the filename you want this template to be saved as

	module.exports = class {
	data() {
	return {
	permalink: outputFile,
